To all whom it may concern:

Be it known that-we, WILLIAM F. GATE- woon and JOHN D. McADAMs, citizensof the United States of America, residing at Pierce City, in the countyof Barry and State of Missouri, and Alton, in the county of Madison andState of Illinois, respectively, have invented certain new and use fulImprovements in Calculating-Machines, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

Our invention relates to a calculating machine, the object being toproduce a very simple and eliicient machine of this character having allof the functions of more complicated adding machines now in use.

The machine herein shown may be briefly described as follows: Itcomprises a totalizer, ten keys bearing the characters 0 and l to 9,inclusive, and a laterally shiftable carriage, the carriage beingnormally out of alinement with the. totalizer and movable step by stepin response to movements of the numeral keys. This carriage is providedwith rack\\bars f or actuating the totalizer, springs tending to movesaid rack bars, and lockingkpawls engaging with teeth on the rack barsto retain them in their normal positions.' Upon the operation of anumeral key, the carriage moves one step in a direction 'parallel to theaxis of the totalizer, and one of the rack bars is then located directlybelow the units wheel of the totalizer. The numeral keys are mounted onkey levers, the ends of which have stops for limiting the movement ofthe rack bars. Depressing a numeral key brings into service a trippingdevice which releases one of the .lookin pawls,

thereby allowing a spring to move t e rack lrack bar to occupy a of thenumeral of the depressed key. Y the next key is depressed, a. secondrack bar bar longitudinally until its engages the stop on the key lever.Releasing the numeral key causes the locking pawl to engage one of therack bar teeth and also disengages the stop on the key lever from therack bar. It will now be understood that operating a numeral key causesthe carriage to move one step,` locates a rack bar directly below theunits wheel of the totalizer, and causes said predetermined abnormalposition according to the denomination When is released and then lockedin an abnormal pos1t1on, according to the denomination of the key,causing the carriage to move another step in response to this keymovement, thereby shifting the first mentioned rack bar to a pointdirectly below the tens wheel of the totalizer, and locating the secondrack bar below the units wheel. This action of the carriage and rackbars occurs at each operation of a numeral key. Depressing the O keycauses the carriage to move one step without releasing a rack bar. Afterthe numeral keys have been operated, the number may be recorded or addedin the totalizer by pulling an operating handle. This handle isconnected withmeans for moving the totalizer wheels into ehfagement withthe rack bars and thereafter restoring said rack bars to normalpositions. Restoring the rack bars while they are engaged with thetotalizer rotates the totalizer wheels a degree corresponding to thevalue of the numeral keys which were depressed to release'the rack bars.The totalizer is moved out of engagement with the rack bars after thelatter reach their normal position and the carriage is then restored toits normal or starting position. Each rack bar is provided with a row ofprinting type bearing the characters 0 and l to 9, inclusive. When therack bars are shifted to abnormal positions, from which they arerestored to add a number to the totalizer, type characters correspondingto said number are alined with a movable platen. During the movement ofthe operatinghandle,the platen is carriedtoward the printing type andthe numerals are printed on a sheet of paper through the medium of aninkingfribbon. In printing a total, the carriage is moved idly a numberof steps corresponding to the number of figures shown by the totalizer,this idle carriage movement being obtained by operating the 0 key, andthe total key is then depressed. Depressing the total key moves thetotalizer into engagement with the spring actuated rack bars andreleases said rack bars, allowing the springs to move them until theyare stopped by mechanism in the totalizer which stops the total wheelsat 0. It is to be understood that the total wheels are -reverselyrotated in taking a total and that the stops just referred to areeffective only during such movement. As the rack bars are only permittedto move while the total wheels arebeing'restored to 0, it will be seenthat the inal position of each rack bar is determined by the startingposition of the total wheel with which it cooperates. The printing typeon the rack bars are therefore positioned to print the total, and theprintingx operation (pay be performed by pulling t e operating andle.

In the accompanying drawings: 1 designates a base plate and 2 and 3,respectively designate side plates secured to the -base plate. The sideplates have extensions 2 and 3', integral with or rigidly secured tocross bars .4 and 5 at the front and rear ends of the machine. All ofthese parts are stationary, their sole function being to provide a framefor the support of the Inovable parts of the machine.

The numeral heya-'The numeral keys are mounted on key levers 6, pivotedat 7, and held in their normal position by springs 8. These key leversare of different lengths and all of them, except those connected to 9,(see Figs. Il and, n hese stops are ard 1n consecutlve numerical orderaccor ing to the numerals of the ke s to whichthey are connected, thenumera key 1 stop bein at thefront of the row', and the numeral ey 8stop being at the back of the row.

lat the front and rear ends of the machine.

A series of rack bars 13, rovided with teeth13, 4(Figs. IV and V areslidably fitted to the longitudinal bars 10 of the carriage frame, saidrack bars having guide lips 14 which overlap the bars 10. `Springs l5,secured to the rear end of the carria e frame, are connected at theirforward ends to the rack bars. These springs are normally under tension,and tend to pull.the rack bars 13 rearwardly when they are free ofrestraint. The rack bars are locked in their normal positions, (shown inFig. V), by pawls 16 pivoted to the carriage at 17 and held inengagement with the rack bars by springs 18. Each rack bar is providedat its front'end with a depending lug 19 and at its rear end with asimilar lug 20. When the carriage is in its normal or starting position,the lug 19 on the rack har at the left hand end of the carriage ispositioned to coperate with one of the key lever stops 9.

Assuming that the numeral 4 key is depressed, as shown in Fig. VI, thestop 9 at the rear end of the numeral 4 key lever will be elevated `andthe locking pawl 16 will be released and held in an elevated p0- sitionby mechanism to be presently described. It will now be seen that the actof depressing thev numeral key releases a rack bar and allows the properspring 15 to move said rack bar until it engages one of the key leverstops 9. When the numeral 4 key is depressed, (Fig. VI), the rack barcorresponding to it moves rearwardly four steps and engages the stop 9of said key lever. Releasing this key lever will cause its stop 9. tomove away from the lug 19 and also allow the pawl 16 to engage a tooth13 on the rack bar. The pawl 16 will then hold the rack bar in anabnormal position, four steps away from its normal position.

The means for releasing a pawl 16 'upon the operation of a key levercomprises a tripping device 21 provided with a tripping projection 22and having rearwardly extending ends 23 which are pivotally supported at24, (Figs. I, II and III). The ends 23 of the tripping device rest on ayoke 25 which extends across the front of the. O and. 5 ly, haveupturned stops the machine and is pivoted at 26 to the side plates 2 and3. Springs 27 engaging the ends of tripping device 21 hold 'said device,and the yoke 25, in the position shown in Figs. II, III and V. The yoke25 is forced into engagement with the upper edges of the numerall keylevers by t e springs 27, and said yoke is therefore elevated duringeach o eration of a key lever. Elevatino the yo e 25 raises the ends ofthe pivoted tripping device 21 and lowers the tripping projection -22into operative engagement with a pawl 16, as seen in Fig. V .When the kelever is released, the yoke and tripping c evice will be restored tonormal position by the springs 27. Operating the yoke 25 through themedium of the key levers. also operates escapement mechanism whichallows the carriage to move toward the left step by step, as will behereinafter described, the object in so movingthe carriage being tolocate the rack bars in alinement with totalizer wheels of the properorder. If one key is depressed, the rack bar at the extreme left will belocked in an abnormal position, as previously described, and thecarriage will move one step, thereby locating said rack bar in alinementwith the units wheel of a totalizer. If another, or second, key isdepressed, the rack bar just referred to will be shifted into alinementwith the tens wheel of the totalizer and the next adjacent rack bar willbe alined with the units wheel. After the carriage has been properlypositioned in response to movements of the numeral keys, the tot-alizeris engaged with the rack bars and the rack bars are then restored tonormal position by means which will be hereinafter described.

)Ve have previously stated that the and 9 keys are not provided withstops for the rack bars. The 0 key lever has a lug 30 on its top edge(see Figs. II and V), which lug engages the rigid cross bar 4 when the l0 key is depressed, and thereby limits the degree of movement of the 0key lever. The yoke 25 is rocked by the 0 key lever so as to operate anescapement and cause the carriage to move one step, but this movement ofthe yoke ,25 is not great "enough to cause the tripping device torelease any pawl 16. The 0 key lever therefore simply provides forstepping movement of the carriage and does not cause any rack bar tomove rearwardly. Operating the numeral 9 key lever shifts the carriageone step, releases the proper pawl 16, and allows a rack bar to moverearwardly until its rear end engages a stop 31 on a longitudinal bar 10of the carriage frame, (see Figs. Iand V), this movement v being ninetimes the amount imparted to a rack bar when the numeral 1\key lever isoperated.

T he means for engaging the trotaZz'c/:er with 'ita actuating decima-Thetotalizer (lFig. IV) comprises a row of toothed whee s 32 looselymounted on a shaft 33, an indicator ring 34 being secured to each wheel32. The

totalizer also includes carryin mechanism and other portsito be hereinater fully described. The totalizer shaft 33 is secured to a verticallymovable frame 35 which partially embraces the frame side plates 2 and 3.This frame is slidably connected to said frame plates by screws 36passing through Y slots in the vertical legs of said frame. Pins 37,rigidly secured to the totalizer frame, pass through slots 38 in theframe side plates, and serve as means for engaging the totalizer framewith devices for lowering it. Springs 39 having their free ends arrangedunder the pins 37 support the totalizer frame in elevated position.After the carriage of the machine moves to the left in response tomovements of the numeral keys, certain rack bars are directly belowtotalizer wheels and the totalizer may be moved into mesh with said rackbars by pulling an operating handle 40. This operating handle is securedto one end of a rock shaft 41 and has a rearwardly extending arm 42. Anarm 43 is secured to the opposite end of the rock shaft 41. A slidablesection 44, having an end wall 45 and side wings 46, is mounted betweenthe frame plates 2 and 3. A cross rod 47 secured to the end wall 45 isconnected to the arms 42 and v43 by links 48. It will now be understoodthat the operating handle is connected to the slidable section 44 insuch manner as to cause the latter to move forwardly when the handle ispulled forwardly.

The wings 46 ofthe slidable section 44 are provided with a pair ofguideways 49 and 50 for the reception of the pin 37 which projects fromthe totalizer frame, (see Figs.

ier

VIII and IX). A pawl 51 provided withA an inclined face 52 is held inthe position shown in Fig. VIII by a spring `.53, the upper end of saidpawl being engaged with the top wall of the guideway 49. lVlien theslidable section 44 is pulled forwardly, the pin 37 on the totalizerframe moves downwardly on the inclined face 52, and said pin 37 iseventually located in the lower guideway 50. This movement `of the pin37 results in downward movement of the totalizer frame and locates thetotal wheels iii engagement with the rack bars 13 in position to beengaged thereby. A continued movement of the slidable section 44 causesits end wall 45 to engage the depending lugs 20 on the rack bars withthe result of pushing said rack bars forwardly to normal positions, andat the saine time cause them to impart ro-tation to the total wheels.The locking pawls 16 allow the rack bars to move forwardly andautomatically lockV said bars when they reach their normal positions.

chine,

The springs 39 which normally hold the talizer frame elevated -areallowed to restore'said frame when the slidable section reaches the endof its forward stroke. At this time the in 37 onthe totalizer framemoves upwar in the space 54 at the rear ends of the gui eways 49 and 50.The slidable 4section may then be moved rearwardly to normal position bythe operating handle. In the event that an error has been made inoperating the numeral keys, the rack bars may be restored to normalposition without operating the totalizer. This action is obtained bymoving the pawl 51 out of alinement with the pin 37, as shown in Fig. X,and thereby allowing the slidable section to operate without depressingsaid pin.

The means for renderin` the pawls 51 ineffective comprises a key at theleft side of the keyboard to which a lever 55 is conneoted, (see Fig.V), said lever being fixed to one end of a transverse rock shaft 56 hav`ing a rocker arm 55 secured to its opposite end. The rear end of lever55 coperates with a pawl 51 at the left side of the mawhile the rockerarm 55 coperates pawl 51 at the right side of the ma- The pawl 51, (seeFigs. VIII and X), is rovided with a lip 57 which lies above tiie rearend lever 55. Depressing the key X will raise the rear end of lever 55and thereby cause the pawl 51 to move from the position seen in Fig.VIII to the position shown in Fig. X.

Means for moving the carriage-The means for moving the carriage includesa sector 60, (Figs. IV and VII), pivoted at 61, and having teeth at itsupper end which engage longitudinal members of the carriage. A feedspring 62, connected to the sector, passes around a pulley 63 at theleft hand side of the machine, and has its rear end secured to the rearend of the slide-ble section 44. A carriage restoring spring 64 is alsoconnected to the sector 60, passes therefrom around a pulley 65 at theright side of the machine, and has its forward end connected to theslidable section 44. The carriage restoring spring 64 is normallyinactive, its coils being contracted so as to exert no pulling actionwhatever on the sector 60. The feed spring 62 is normally under tensionand tends to pull the carriage toward the left hand side of the machine.Upon the operation of the key levers, an escapement device, which willbe presently described, isbroughtinto service to allow the spring 62 tomove the carriage to the left, step by step. When the slidable s ection44 is pulled forwardly-by the operating handle-40, (see Fig; VII), therear end of the feed spring 62 moves forwardly and the forward end ofsaid spring also moves forwardly. This movement results in relaxation ofthe'feed spring and places the carwith a chine.

riage restoring spring under tension. The sector 60 therefore moves tothe right and restores the carriage to normal position when the slidablesection reaches the end of its forward stroke. The carriage is locked inits normalA or starting positlon b escapement mechanism. tion is movedrearwardl to normal position by the operating handle, the s rin s areyagain located as seen in Fig. V w erein the restoring spring 64 isrelaxed and spring 62 is under tension.

The escapement mechanism, (see Figs, XVIII to XXI), comprises a yoke 66,which partially embraces the rear end of the machine, the forward end ofsaid yoke overlapping the yoke 25. The yoke 66 is pivoted at 67 to theframe side plates 2 and 3, and held in normal position .by a spring 68.Each yoke 25 and 66 is provided with a row of vertical teeth 69, and arow of alined horizontal pins 70. One of the pins, 70 on each yokenormally engages the end of a pawl 71, pivoted at 72 to a plate 73 whichis secured to the carriage. Upon the operation of a key lever, the frontend .of the yoke 25 moves upwardly, with the result of imparting arocking movement to the yoke 66. This upward movement locates one of theteeth 69 in alinement with an abutment 74 on the plate 73 and at thesame time disengages the pin 70 from the pawl 71. The carriage thenmoves under the influence of spring 62 until the abutment 74 engages atooth 69, (see Fig. XX), and when the ke lever is released, the toothedend of eac escapement yoke moves downwardly, thereby releasing the`-teeth 69 from the abutments 74 and locating the next adjacent pin 70in alinement with the end of a pawl 71. It will therefore be understoodthat the operation of a key lever allows the carriage to move one step,the operation just described being repeated each time a key lever isdepressed and afterward released. The pawl 71 isheld against a stop 71by a spring 73. When the carriage is restored to normal position, the'spring pressed pawl 71 moves under the row of pins 70 and finally stopsin the position shown in Fig. XIX, where it y holds the carriage in itsnormal position.

The totaliser--A carrying dog 75 is locat-ed 'adjacent to each of thetotal wheels 32, and each of said wheels carries a lug 76 whichcoperates with one of the carrying dogs. The carrying dogs 75 aresupported by a engages a shoulder 78 near t-he lower end of each dog,and a slotted plate 79 that engages the rear edges of the dogs. Theabutment 77 is preferably a rigid bar arranged parallel to the axes ofthe total wheels and constituting a support for the series of carryingdogs. A comb shaped plate 81 pivoted at 82 separates the upper ends ofthe When the sli able secframe having a bar77 that `frame side vplate 2.

dogs, said plate 81 having an arm 83 'at lies against the outer face ofthe The upper ends of the dogs 75 are provided with projections 84overlying the teeth of the comb plate 81. When the totalizer is in itselevated position, the slotted lower end of the arm 83 is locateddirectly above a pin 85 on the frame side plate 2, and when thetotalizer is lowered to engage therack bars, said pin 85 is located inthe slotted lower en d of the arm 83, (see Fig. XIV), and the comb plate81 to which said arm islsecured is spaced a slight distance away fromthe projections 84 on the carrying dogs. A spring 86 tends to rock thearm 83 to the position seen in Fig. XV, and therefore holds said armengaged with the pin 85, as shown in Fig. XIV, when the totalizer islowered. Each carrying dog has a rigid foot 87 arranged in the path ofmovement of a lug 76 on a totalizer wheel. Each dog also has a tooth 88located directly above a tooth on the next adjacent `totalizer wheel.When a totalizer wheel moves from 9 to 0, its lug 76 engages a foot 87of a carrying dog, with .the result of shifting said dog laterally andreleasing it from the abutment 77, thereby allowing the correspondingspring 80 to move the dog downwardly the slight distance, this downwardor longitudinal movement being limited by a combsplate 81 which thenengages the projections ,84. l/Vhen the totalizer is elevated andreleased from the rack bars, the armv83 is disengaged from the pin 8.5and a spring 80 then moves the carrying dog downwardly to the positionseen in Fig. XV. During this downward movement, the tooth on thecarrying dog engages the adjacent totalizer wheel and rotates it onestep. The tripped carrying dogs are elevated to normal position duringtherearward stroke of the slidable section 44 through the medium ofalever 90, pivoted at 91 to the frame side plate 2, (Figs. XIV and XV.)The lever 90 is rocked by the rod 47 at the rear end of the slidablesection, while the latter is moving rearwardly, and this rockingmovement shifts the lever 90 from the position shown in Fig. XIV or XV,where it willfallow the arm 83 to swing rearwardly to the position shownin Fig. II, where it holds said arm in its normal position. Obviouslythis operation of the lever 90 will cause the pivoted comb 81 secured tothe arm 83 to restore the tri ped carrying dogs to normal position.

pring pressed detents 92 are pivoted to the totalizer frame and serve tomaintain the total wheels in proper linement.

Each totalizer wheel indicator ring 34 carries a lug 93, (Fig. XIV andFig. XV), which engages a shoulder on a spring pressed pawl 94 when thetotal wheel stands ati 0. This pawl isy only brought into service inclearing the machine or printing a total, as will be hereinafterdescribed.

The lprnting mechanism- 95 designates a printing mechanism frame,pivoted at 96 to the frame side plates 2 and 3, said frame having wings97 at its rear end that support a spool 98. A strip of papel' 99supplied from spool 98 passes under a platen 100, rigidly secured to theframe 95, and from thence it is deflected upwardly and `rearwardly by apair of feed rolls 101 and 102. The frame 93 is rocked on its pivots 96to perform a printing operation by mech anism controlled by theoperating handle 40. Each rack bar carries a row of printing typebearing the characters 0 and 1 to 9, inclusive, (see Figs. I and VI).

beyond the end of the platen 100, see Fig. IV, which shows that theplaten terminates at 100. An inking ribbon 103 is located below theplaten and above the type characters. It will be evident from theforegoing that all of the rack bars are normally out of alinement withtheplaten. As the carriage moves toward the left in response to numeralkey movements, the rack bars move to that is to say, all rack barsalined with the totalizer are alined with the platen. The type character0 appears at the end of each rack bar below the inking ribbon, (Fig. I),and as depressing the 0 key steps the carriage without releasing a rackbar, the type character 0 will move into alinement with the platen uponthe operation of the 0 key. The type characters are arrangedconsecutively, and when a numeral key is depressed, the rack bars areshifted to locate a type character corresponding to the key numeral inalinement with the platen 100. For example, if the numeral 4 key isdepressed, as seen in Fig. VI, the proper rack bar moves rearwardlyfour'steps and the type character 4 is then alined with and beneaththe.platen. The printing occurs during the first part of the movement ofthe operating handle before the rack bars begin to move forwardly, andthe printing action is caused by lowering the printing mechanism frame95. A spring 104 holds the frame 95 in the position shown in somedistance above the rack bars.

We will now describe the means for lowering the platen toward the type,this means being most clearly shown in Figs. VIII to .XIII, inclusive.These figures show only one wing of the slidable section, but it will beunderstood that the wing of the opposite side thereof includes the sameelements. Each side plate of the printing mechanism frame 95 carries apin 105 that engages the upper end of an operating lever 106, said leverbeing pivoted at 107. A. spring 108 points directly below the platen100;.y

These type characters are normally located Fig. VIII wherein the platen100 is located holds the lever 106 against the pin 105. The' slidablesection 44 carries a pin or' lug 109 and as this section is movedforwardly by the operating handle, the pin 109 engages the lower end ofthe lever 106, imparts a rocking movement thereto, and thereby moves theprinting mechanism frame 95 downwardly. This action moves the parts tothe position shown in Fig. XII wherein the platen has been moved toprinting position. A continued movement of the slidable section 44releases the pin 109 and allows the spring 104 to restore the rockableframe 95. While the slidable section 44 is being restored, the pin 109strikes the lever 106 (Fig. XIII), imparts a slight idle rockingmovement thereto, and then passes through a groove 110 in the lower endof said lever. The groove 110 is shown most clearly in Fig. XI. Thelever 106 is provided with a finger 111 which rests on a yieldable lip112 at the upper end of the key controlled lever 55. This yieldable liphas no function during ordinary operations of the machine, the finger111 being forced downwardly therefrom during the forward movement of theslidable section 44, and

afterward restored to the position seen in Fig. VIII, when the printingelements are restored.

The key X, referred to in describing the totalizer, is also adapted torender the printing mechanism inoperative. The key levers 55 and 55',which are connected to the key X each have a lip 112 that lies` belowthe finger 111 on an operating lever 106. When the key X is depressed,the rear end of key levers 55 and 55 are elevated and the operatinglever or platen shifter 106 then occupies the position seen in Fig. X.Moving the operating lever to this position allows the pin 109 on theslidable section 44 to pass through the groove 110 without actuating thelever 106. Depressing the key X therefore allows the operating handle 40to move the slidable section without operating the printing mechanism.This key also prevents the totalizer from moving into mesh with the rackbars, as previously described, and byiaving these two functions itserves as an error key.

The strip of paper 99.is fed during each operation of the handle 40 byrotation of the feed roller 102 a slight distance. This feed roller ismounted on av shaft 113 having a. toothed wheel 114 secured to one ofits ends, (see Fig. III.) A feed pawl 115 pivoted to the upper end of alever 116 is held in engagement with the teeth of wheel 114 by a spring117. The lever 116 is pivoted at 118 to the side plate 3, and it is heldagainst a stop 119 by a spring 120. When the slidable section movesforwardly, the rod- 47 carried thereby engages the lower end of thelever 116, imparts movement thereto and thus causes rotation of thetoothed wheel 114. During the rearward stroke of the slidable section44, the lever 116 and pawl 115 are restored by the spring 120.

The total key- The total key is secured to a rockable U-shaped lever 121having its ends pivotally connected at 122 to the side frame plates 2and 3, respectively. The total key lever has a long flange 123 whichconstitutes a tri ping device for releasing the pawls 16. Tliis trippingdevice is Similar to the tripping device 22 that releases the pawls 16when the numeral keys are depressed, but it is located so as to releasethe pawls only when their adjacent rack bars are alined with thetotalizer. The total key lever also has projections or lips 124 thatrest on the pins 37 which project from the totalizer frame, (see Figs.II, III and IV.)

In printing a total, the carriage is moved idly a number 0f stepscorresponding to the number of figures in the total, the latter beingindicated by the indicator rings 34. After positioning the carriage, thetotal key may be depressed with the result of movinlg1 the totalizerdownwardly into mesh Wit rack bars, through the medium of theprojections 124 resting on the pins 37 which project from the totalizerframe. Depressing the totalizer key also causesits tripping device 123to release all of the rack bars that are in mesh with total wheels. Vhenthe rack bars are so released, they are pulled rearwardly by the springs15 until the lug 93 (see Fig. XV), on the numeral ring engages ashoulder on the spring pressed stop 94. The total wheels are rotatedreversely during this rack bar movement and when stopped by the member94 they stand at 0. It will therefore be seen that the movement of eachrack bar is determined by the position of the total wheels which it oerates; for example, if a total wheel stan s at 4, the rack bar isallowed to move rearwardly four steps and the typev character 4 is thenpositioned directly below the platen. All of the release rack bars arepositioned accordingly, and the type characters are positioned to printthe total. The printing may then be performed yby rocking the handle 40as previously described. If the total key is held depressed during thehandle movement, the totalizer will remain in engagement with the rackbars and the total will again'be inserted in the totalizer. Thetotalizer may be cleared by releasing the rack bars through the mediumof the total key, as just described, then releasing the total key todisengage the cleared totalizer from the rack bars, and thereafterdepressing the key X while the handle 40 isv being operated.

The inking ribbon is preferably provided .with ink ofA two differentcolors, or oomin a bracket 132. Each rod is provided with posed of twoseparate ribbons of different colors. This ribbon is wound around spools125 supported by the frame 95, and it may be automatically fed from oneoolto the other in any suitable manner. he ribbon spools 125 areslidably mounted on rods 126, and prevented from accidentall shiftingthereon by springs 127 When e total key is de ressed, the ribbon spoolsare automaticalll;T shifted to cause the total to .be printed in adifferent color from the column of figures. The means for shifting theribbon spools comprises a pair of bell crank levers 128 pivoted at 129and having feet 130, which extendunder the total key lever. Each bellcrank leverv is connected to a rod 131, having its rear end slidablymounted a projection 133, which ergages a ribbon spool, (see Figs..v Iand I When the total key is depressed, the bell crank levers 2 128 arerockedy to impart a longitudinal movement to the rods 131, therebyshifting the ribbon s ools so as to print the total in ink of a di erentcolor from that used in printing the other items.
